The Cow - 2:177
It is not good that you turn your faces towards the east or the west. The righteous are those who believe in Allah, the Last Day, the angels, the Book and the Prophets, and they give freely to relatives, orphans, the needy, the stranded, the beggars, and to free the slaves, and they observe the prayer, and pay the zakat, and keep their word when they contract, and they resist hardship, distress and oppression. It is they who are the righteous, and it is they who are the virtuous.
They believe in angels:
The Family Of Imran/3:80
Nor does he command you to take the angels and the prophets as gods. Does He ever command you to disbelieve after you have become Muslims?
The Family Of Imran/3:124
"You were saying to the believers: "Is it not enough for you that your Lord supports you with three thousand angels sent down?"
The Women/4:136
Believers! Believe in Allah and His Messenger and the Book which He sent down to His Messenger and the Book which He sent down before. Whoever disbelieves in Allah, His angels, His Book, His messengers and the Last Day has gone astray.
